Tech Tips: If you have ever looked closely, you would notice a specific code written on the back of a phone charger that begins with the letter 'R'. This is followed by a dash and a series of numbers.

Nowadays, when purchasing a smartphone, a charger is often not included in the box. Consequently, people are forced to buy a charger separately—and that is precisely where the real trouble begins. The market is flooded with inexpensive and counterfeit chargers, making it challenging to distinguish between reliable and unreliable ones. Amidst this confusion, a small code—which most people tend to overlook—can prove to be of immense help.

As mentioned, if you examine a phone charger closely, you will find a specific code on its back that starts with 'R', followed by a dash and some numbers. This is no ordinary number; rather, it is an official registration code. This code is issued by the Bureau of Indian Standards (BIS). This certification is mandatory for all electronic products sold within India. It signifies that the charger meets the safety and quality standards established by the government.

This 'R' code indicates that your charger is both registered and certified. If a charger bears this code, it implies that it complies with safety standards and is neither counterfeit nor of substandard quality.

Conversely, chargers that lack this code—or display an incorrect one—can be hazardous; they may pose a threat to both your smartphone and your personal safety.

If you wish to be absolutely certain, you can also verify this code online. You can do so by using the 'BIS Care' app or by visiting the official BIS website. All you need to do is enter the code printed on the charger, and the complete details associated with it will be displayed instantly. This allows you to determine immediately whether the product is genuine or not.

By checking this code, you can ensure that your charger is safe and can be used for the long term without posing any risks. Using the correct charger significantly reduces the risk of issues such as overheating, short circuits, or electric shocks. Furthermore, it safeguards both your smartphone's battery and its performance.

The next time you purchase a new charger, pay more attention to its 'R-code' than to its price. This small number can prove to be immensely important—both for your safety and for your device.
